Blender - Chevron Markings - Design
Starting with the default cube, scale it in the Z direction to make it quite flat (say to 0.05). Extrude two adjacent faces to make a chevron with very long arms.



Add an Array modifier and configure it to repeat the single chevron at the required spacing. You can use the Constant offset to manually adjust this.



Create a second mesh to enclose the region where you want the chevrons. This must be manifold - ie, it needs to fully enclose the space.



Select the original mesh (the chevrons) and add a Boolean modifier set to Intersect with Object set to the bounding mesh you just created.

Select the bounding mesh and Hide it by pressing H and you should now see just the chevrons that were within the bounding box. 



Finally, you can Apply the modifiers and delete the bounding mesh as it's no longer required.
